I don't have much confidence in my ability to help solve it for you beyond
the detection problem, but did you try the "aspect" lavc option?

I might do better if you could make some source video available.

Example from http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-vcd-dvd.html

-vf scale=640:480 -lavcopts aspect=4/3

The vpass option for lavc seems superfluous because you're apparently making
only one pass.
